١۔ كِتَابُ الطَّهَارَة
[Machine] A group of people came to the Messenger of Allah ﷺ and said, "Inform us about finding water in the sea, while we have only brackish water with us. We may fear thirst, so is it permissible for us to perform ablution with the salty sea water?" He replied, "Yes, perform ablution with it," and he mentioned the narration.
أَتَى نَفَرٌ إِلَى رَسُولِ اللهِ ﷺ فَقَالُوا أَخْبِرْنَا نَصِيدُ فِي الْبَحْرِ وَمَعَنْا مِنَ الْمَاءِ الْعَذْبِ فَرُبَّمَا تَخَوَّفْنَا الْعَطَشَ فَهَلْ يَصْلُحُ أَنْ نَتَوَضَّأَ مِنَ الْبَحْرِ الْمَالِحِ؟ فَقَالَ نَعَمْ تَوَضَّئُوا مِنْهُ وَذَكَرَ الْحَدِيثَ
